CLOVER-HULLER.

SPECIF-IATION forming part of Letters Patent No. 738,646, dated September 8, 1903. Application filed June 30, 1902. Serial No. 113,791. (No model.)

To all whom it may concern Beit known that I, Lnwrs STANLEY WHIT- ING, a citizen of the'United States of America, and a resident of Mansfield, Richland county,

Ohio, have invented certain new and useful Improvements in Olover-Hullers, of which form, and regular means of feeding the clover to the hulling-cylinder irrespective of the condition of the clover; second, to construct a separator with scrapers that will perform the double function of forcing the clover for- 2o ward into the cylinder and of bracing the longitudinal bars which are attached to the lower portion of each separator-trough; third, to

provide a simple and efiective scraper that will add strength and rigidity to the longitu- 2 5 dinal bars to which they are attached.

It is well known to those skilled in the art that the depending pins which are secured to the longitudinal bars do not feed the clover to the hulling-cylinder in uniform quantities when the clover is wet, resulting in clogging or choking the separator and cylinder and bending orbreaking the depending pins. The con struction of my scraper obviates the defects described.

I attain these objects by the scraper illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a huller with the sides partly broken away, showing the location of thetroughs with my improved feeding-(scraper attached. Fig.2 is a sectionalside elevation of one of the series of separator troughs, showing the feedingscraper attached to the longitudinal bars. Fig. 3 is a top sectional view of one of the .series of separator-troughs. Fig. 4 is an end view of one of the separator-troughs, showing the feeding-scraper attached. Fig. 5 is a bottom view of one section of the series of troughs, partly broken away, showing a series of feeding-scrapers secured to the longitudinal bars in alinement with each other. Fig.

6 is a front view of the feeding-scraper, showing the sides formed triangular in shape and extending forward at right angles therewith, 5 5 forming a pocket. Fig. 7 is a side view of the feeding-scraper, showing a portion of the back projecting above the plane of the top and adapted to fit in suitable grooves provided in the longitudinal bars; and Fig. 8 is a bottom plan view of the feeding-scraper.

The framework 2 of the huller has a feedtable 3 attached to the front end which cornmunicates with the threshing-cylinder 5. The material is fed to the threshing-cylinder and after passing through is delivered on top of the separator 6. This separator is composed of a series of troughs 7, which are journaled upon crank-shafts 8 8 and are driven by a belt passing over a pulley journaled on the end of said shaft and a pulley journaled on the end of the cylinder-shaft 9. When motion is imparted to the crank-shaft upon which each section of the series of troughs is journaled, an oscillating motion is imparted to each section, carryingthe straw on the surface of the separator to the rear and thoroughly separating the tailings and pods from the straw. The seeds and pods drop through the apertures 14 in the troughs to the inclined 8o floor 13. v

The clover is fed into the balling-cylinder 10 bymeans of the feedingscrapers ll,which areattached to the longitudinal bars 12 of each section of the troughs, and as motion is transmitted to the troughs the scrapers 11 move over the surface of the inclined floor 13 and deliver the material to the hulling-cylinder, which lies below the inclined floor at its lower end, the latter having a hopper Leading go to the hulling-cylinder. The front portions of the separator-troughs are provided with ap,-- ertures 14, while the rear portion is provided with twoseries of inclined slats 15. These slats swingon pintles 16, and the openings are 5 varied by means of a draw bar 17, which is connected to the upper portion of the inclined slats. The sides 18 of the trough are notched or serrated upon the upper surface 19 and are provided with pins secured to each notch or serration. To the lower portion of each trough the two longitudinal bars 1212 are attached,

leaving a space between them. To the lower surface of these longitudinal bars my improved feeding scraper is attached. The scraper is preferably made of sheet metal. The sides 22 extend inwardly at right angles with the body portion 23 of the scraper and are triangular in shape. The upper portions 24 of the sides extend inwardly slightly below the plane of the top 25 of the body portion of the scraper and are adapted to be attached to the lower edges of the longitudinal bars. The margin 25 of the body portion is fitted to suitable grooves A in the bars. This construction of a feeding-scraper forms a pocket by means of which the pods,tailings,and seed are forced forward over the surface of the inclined floor uniformly and positively irrespective of the condition of the clover as to its being wet or dry. The feeding-scrapers are attached at regular intervals to the longitudinal bars with the sides forming the pockets extending toward the hulling-cylinder, and the blade or body portion of the scraper is at right angles with the longitudinal bars. The body portion of'the scraper is made integral with the inwardly-extending upper portion of the sides,

- said upper portion being attached to the bars by any suitable fastening means. This, in effect, constitutes a series of braces which give rigidity and strength to the bars not otherwise obtained by the depending pins, which are secured to the longitudinal bars in the ordinary wav.

' It will be noted that, by reason of the novel construction of my feeding-scraper, the usual I claim, and desire to secure by Letters Pat- I out, is-

l. Afeeding-scrapercomprisingabodyportion, flanges formed on the body portion, the flanges gradually converging toward one another, the flanges gradually increasing in width from the bottom to the top of the body portion, the upper portions of the flanges bent with relation to the body portion and t0 the flanges, the flanges and their upper portions cooperating with the body portion to form a pocket in the upper end of the scraper.

2. A scraper comprising a body portion or back and flanges or sides connected to the side edges of the back, the breadth of the flanges increasing from the bottom to the top thereof, the length of the flanges being greater than the height of the back or body portion of the scraper, the upper wider ends of the flanges bent over at an angle with the remaining portions of the flanges and of the back or body portion of the scraper and means for secur ing the scraper to a suitable support.

3. A scraper comprising a body portion,

angular connected flanges located on the body portion, the width of the flanges gradually increasing from the bottom to the top of the body portion, the inwardly-extending portions of the flanges cooperating with the remaining portions of the flanges and with the body portion to form a pocket in the upper end of the scraper, the inwardly-extending portions of the flanges attachable to a suitable support.

4. A scraper comprising a body portion or back, and flanges secured to the side edges of the back, the flanges each bent angularly intermediate their length and located at an angle to the back, that portion of the back adjacent the flanges cooperating with the bent flanges to form a plurality of three-sided pockets.

5. In a separator, the combination with a movable trough and bars secured longitudinally thereof, the bars having grooves or recesses formed therein, of ascraper secured to the bars, the scraper comprising a body por tion and flanges secured thereto, the upper portions of the flanges bent inwardly toward one another and lying at an angle to the remaining portion of the flanges and to the body portion, the upper margin of the body portion projecting above the inwardly-bent portions of the flanges, the upper margin received in the grooves in the longitudinal bars, the inwardly-extending portions of the flanges secured to the bars.

6. In a separator, the combination with a movable trough and longitudinal bars carried thereby, the bars having recesses formed therein, of a scraper secured to the bars, the scraper comprising a body portion, flanges secured to the body portion and forming pockets in combination therewith, and a margin projecting above the pockets, the margin received in the grooves formed in the bars.

7. In a separator, the combination with a movable trough and longitudinal bars carried thereby, the bars having recesses formed therein, of a scraper secured to the bars, the scraper comprising a body portion, flanges secured to the body portion and forming pockets in combination therewith, and a margin projecting above the pockets, and in alinementwith the body portion of the scraper, the margin received in the grooves formed in the bars.

8. A scraper comprising a body portion and flanges secured thereto, the flanges triangular in shape and bent transversely, constituting two sides of a pocket, the remaining secured to the bar, the scraper comprising a a body portion and a flange secured thereto,

the flange bent transversely of its length, to

form two closed sides of a pocket, the body portion cooperating with the flanges to form the remaining closed side, the upper,trans-i versely-bent portion of the flange lying on a plane below the upper edge of the body portion to which it is secured.

11. In, aseparator, the combination with a movable trough and grooved bars secured thereto, of a scraper comprising a body portion depending at an angle to the bars, and a flange formed integrally with the body portion and extending outward therefrom and parallel with the bars, the flange located be neath the upper edge of the body portion whereby a margin is provided, the margin receivable in the grooves in the bars, the flange secured to the bars.
